The aim of this section is to provide a brief self-contained description of the Mayer-Vietoris spectral sequence. We refer to [1]} and adapt the construction to the case of cell complexes.
Since the Mayer-Vietoris spectral sequence is a particular case of a spectral sequence associated with a double complex, we briefly recall this standard construction which is included in most books on homological algebra (see for example [2]}, [3]}, [4]}).
